The confined ground seismic damper is ground seismic dampening technology that softens the impact of earth movement and minimizes displacement of structures, by confining the ground with a continuous wall made of Implant Structures.

Liquefaction is controlled by enclosing the area surrounding the installation site with sheet piles, without having to apply treatment to structures such as facilities, railways, roads, etc. that cannot normally escape damage caused by liquefaction. A simple process that can be done in a shorter period of time and at low cost, and furthermore, can restore the ground to its original state by simply extracting sheet piles, so this method is a countermeasure for liquefaction while being friendly to the earth. This can be used as a countermeasure for liquefaction for all manner of existing infrastructure, whether it be above or below the ground.

With the synergistic effect of the Ring Method, which is used to control liquefaction by cylindrically enclosing the installation site of outdoor storage tanks such as those at a Petrochemistry complex, and the Lateral soil flow restraining pile method, which minimizes the lateral flow of surrounding ground, the entire facility is kept safe.

The embankment construction method has been widely used since ancient times, but has disadvantages, such as requiring a large amount of soil, which is taken from countryside areas with an abundance of nature, using a lot of energy, and requiring a lot of effort and time. Accordingly, we constructed a retaining wall with high earthquake resistance, by pressing in structural　members produced at the plant with the minimum necessary soil. Instead of using soil inside the wall, we used PET bottles, urethane waste, plastic, etc, and so were able to complete the embankment rapidly without causing any further damage to the nature.

Towards the end of the 20th century at the dawn of the IT age, intelligent buildings were born one after another in cities. In the 21st century, in response to the rapid progression of IT, it is predicted there will be the advent of an age of super intelligent buildings with built-in underground shelters for protecting the irreplaceable assets of companies, such as the lives of employees and supercomputers. A lesson from the 9/11 terrorist attacks that shook the world was that it is necessary to be ready to deal with threats such as chemical and biological weapon attacks and cyber terrorism, as well as natural disasters such as fire and flood. Trust is impossible for companies that cannot guarantee safety. This should become common sense in the 21st century.

Provided you have an antiseismic foundation using an implant structure, it will function as a support for the building in normal times, while the internal space can be used for various purposes such as meeting rooms and underground parking, and in times of emergency, it can be used as an underground shelter.
